You should look into following the University of Arizona's Pride of Arizona marching band Ern...if you liked Michigan's musical choices. The U of A band is truly one of the best, most well respected college marching bands in the country among the music circles...but a lot of the general public does not know them as such simply because their football team has never risen to national prominence, thus allowing their marching band to share some of the national spotlight and attention. Yes...I was a member for many years...but they really are among the best in what college bands have to offer. See below.
Since under the direction of Prof. Jay C. Rees (1995-present), the band calls itself the "World's First Alternative Music Marching Band." It is a drum corps style marching band, which movies and visually interprets the music contstantly with the military glide step.
A couple years ago, they performed a show entirely of Led Zepplin music.
These shows are long, 15+ minutes of constant music and difficult marching. Their unique custom shows are very demanding of the performers and filled with artistic interpretation and symbolism. They really have taken the college marchine band idiom into the realm of being "artistic expression." But...since there is little time to perform their entire shows at football games...usually they only get to do bits and pieces of it at these venues for haltime crowds. They are fequently invited to perform their entire show at exhibition performances of drum corps and national high school band competitions such as the national Band of America competition (BOA).
There is a wikipedia entry which mentions some of the band history and also lists their recent shows under Prof. Rees.
You will find a lot of video on Youtube if you search for "Pride Of Arizona". Here is part one of their Zepplin show from 2005. http://www.youtube.com/watch?v=7yTpKjvchfk
You can find part 2 and part 3 on there as well. Of course, when doing the whole show at a venue like Band Day competition in AZ...all the parts are done together continuously to make one long show.
As soon as the U of AZ football team makes it to the Rose Bowl (or another prominent Bowl game)...you will see the U of A band wowing audiences on national TV as well.
